A method for minimizing circulating current and balancing power transformer in loop distribution line of an industrial park is proposed. The proposed method uses a series type Back-To-Back (BTB) converter in loop distribution line of industrial park. Loop distribution line is formed by tying end of two radial lines by a looping wire. Looping wire has a re-closer circuit breaker to localize fault inside loop. Operation of the circuit breaker depends on the zero sequence voltage and current detection of series type BTB converter. This proposed method solves the problem of heavily loaded and lightly-loaded lines condition in distribution line autonomously, which results in lower utilization of transformers and increases losses in electricity system of the industrial park. By employing this proposed method, effective utilization of apparatus is realized by minimizing circulating current and balancing power of transformers in loop distribution line. Analysis and simulation results to validate the proposed method are presented in this paper.

“…The DVC algorithm used for mitigation of balanced dips [9] is a cascade controller, using two vector-control loops i i and i u that tracks the reference voltage of the LC-filter capacitor * c u . This DVC algorithm is implemented in the rotating dq-frame, where the d-axis is synchronized to the grid-flux vector and uses a sampling time of T s (1/f s ).…”

Voltage dips due to faults are considered the most critical power quality problem to sensitive industrial loads. The voltage source converter, connected in series with the grid as a static series compensator (SSC), is suited to protect sensitive loads against such disturbances. This paper proposes a fast control algorithm to improve the dynamic performance of the SSC. Because most faults are single-or double-phase, this algorithm uses a fast technique for separating positive and negative sequence components of the supply voltage, which are then controlled separately. Thus, two controllers are implemented for the two sequences, each based on double vector control, i.e. constituted by a voltage-control loop and a currentcontrol loop. The validity of the proposed algorithm is demonstrated through PSCAD/EMTDC simulation, when the grid is subjected to unbalanced three-phase voltage dips. 904 0-7803-7420-7/02/$17.00 he also works part-time at ABB Sweden, where he is involved in the development of Light-concept devices. His interests are control of grid-connected converters, wind power and power quality.
